As information surrounding medical procedures, policies and practices becomes widely available via the Internet and other mass media entities, consumers are becoming empowered to make their own healthcare choices. Today s patients demand: Faster medical response with reduced waiting times Information accuracy, delivery and availability Safe, secure hospital stays with all the comforts of home State-of-the-art procedures for improved results, reduced pain and faster recovery Digital access to the latest medical information and results Ti-1179 the quality of care to meet consumer demands is compounded by longer life expectancy, increased chronic disease, an aging population and the administration expenses of complying with the latest healthcare codes and regulations.

This has caused healthcare costs to steadily rise for several years. BEA measures cost by major type of product healthcare services and ita-1179 major function healthcare goods and services. In addition to goods and services, HHS measurement includes investment in medical equipment and structures and is the broadest measure of healthcare spending.

Healthcare facilities are deploying a wide range of advanced clinical and non-clinical applications and systems that optimize the delivery and access of healthcare information; enable better communication between staff, providers and patients; enhance patient safety, security and satisfaction; and lower a facility s overall cost of operation. Some ttia-1179 the latest clinical and non-clinical applications and systems include: As more healthcare anxi and images shift to digital format as opposed to paper and traditional X-ray film, clinical information systems need to support fast transmission, and access of information and images.

Patient Monitoring Systems are dedicated systems that monitor breathing, heart asi activity and other vital signs, and issue alarms when these vital signs fall outside certain parameters. Individual monitors at each patient bed are connected to nurses stations and often to a central monitoring station. More sophisticated versions may also include a video system for visual observation of patients. Interactive Patient Systems use a patient s in-room television or computer-based bedside terminal to create two-way interactive communication that provides patients with access to entertainment and medical information and allows them to order meals, schedule a case worker or spiritual counselor, or request blankets, pillows and other items.

An interactive patient system can make facility operations more efficient by reducing the number of non-clinical requests, allowing caregivers to focus on providing care. Nurse Call Systems are no longer limited to the function of calling nurses. A nurse call system may be used to notify doctors, nurses, orderlies, wait staff, or other staff.

In addition, the system may notify ani using designated tones, lights, voice communication, text messaging, or other forms of communication. Typically, a nurse call system can interface with a facility paging system to annunciate code calls or to page specific staff.

Voice Systems are a vital part of any facility. To reduce cost and increase efficiency, healthcare facilities are increasingly adopting Voice over Internet Protocol VoIP technology where voice signals are digitized and transmitted over the network.

VoIP offers many advantages, including instant messaging, call forwarding, conversation encryption and recording, and reduced cost by eliminating long-distance fees. Communication Systems include overhead paging, operating room sound systems, public address systems, and cath lab intercom solutions for staff to have total hands-free communications.

These systems are used to communicate with patients and update facility personnel on abnormal or emergency conditions, changes in facility status, or other major events. Security Systems, including surveillance, access control and life safety alarm systems are a critical part of healthcare facilities. Some areas require security measures to limit access to authorized users, prevent unwanted visitors, avoid possible infant abduction or track specific equipment or individuals.

This has created the need for facility-wide access control systems, monitoring sensors and technologies like mother-infant matching systems, infant abduction systems ita-1179 senior elopement systems using Radio frequency Identification RFID technology.

Modern-day BAS are comprised of intelligent electronic devices that are able to significantly increase operational efficiency by monitoring system performance and providing notification over the network to computers and wireless devices. Audio-visual AV Systems are often deployed in larger healthcare facilities to provide full audio and video capabilities in auditoriums, conference rooms and common areas used for medical seminars, meetings, video conferencing and entertainment. AV applications in a healthcare facility could include such technologies as large flat-screen TVs that act as virtual windows in areas where patients cannot be exposed to tia-179, or large digital signs that provide information on available services or emergency room waiting times.

Facilitate the deployment of new clinical and non-clinical systems and applications across facilities Enable mobility for healthcare providers, non-clinical staff and patients Allow for remote monitoring of systems, equipment and patients Simplify command and control of building automation systems via a non-proprietary protocol Reduce the complexity of managing multiple independent infrastructures er the healthcare facility s overall cost of operation Migrating Towards IP Convergence Advanced healthcare applications and systems operate over low-voltage cabling infrastructures and are increasingly communicating via Internet Protocol IP over converged Ethernet-based networks that optimize efficiency.


As the foundation for all communications, a converged anis ties all healthcare applications and systems together along one or more infrastructures, providing the bandwidth, signal performance and scalability required.

Allow flow of information and integration between applications and systems to enhance patient care The non-converged layout depicts seven dedicated infrastructures supporting seven systems.

The converged diagram shows five of the systems on an IP-based Ethernet infrastructure, while the Nurse Call and Fire systems remain on dedicated infrastructures to comply with regulations. For example, with clinical systems like patient monitoring systems increasingly being connected to IP converged networks, healthcare providers can view and analyze patient information from remote locations. IP-based overhead paging systems with amplifiers and intercoms connected to tia-1197 network can be managed via paging software that resides on a network computer.

While some non-clinical systems like fire alarm systems are required to remain segregated on their own network, others are increasingly running over IP converged networks, such as IP-based surveillance cameras and access control panels that can interface with other applications residing on the network.

Some Ansl systems remain proprietary, but most centralized control units now include an IP network connection for monitoring and controlling BAS via computers or wireless devices.

To tia-11179 the latest healthcare applications and migrate to IP converged networks, healthcare facility, security and information technology managers must work together to ensure that the supporting cabling infrastructure is designed and deployed to provide optimal performance levels, as well as the flexibility to support future applications and growth without having gia-1179 make significant costly changes to the infrastructure.

As the foundation of a converged IP network, the cabling infrastructure must ensure resiliency, reliability for maximum uptime, ani easy implementation and management of new applications. TIA Healthcare Standard vs. Work Area Location TIA does not require outlets to ansl located together and location of outlets should consider the various uses.

For example, while commercial building standards annsi outlets at 18 inches above the finished floor, outlets in healthcare facilities may best be located at bedside height to support patient monitoring, nurse call and other systems. Work Area Outlet density TIA recommends higher work area outlet densities based on the function at tka-1179 location see other sidebar.

Commercial building standards recommend only a minimum of two work area outlets. The standard also states that TEs may be a better option for ICR areas and should be a suitable material when installed in surgical and other sterile environments.

Security and Segregation TIA recommends the use of segregated networks when necessary to ensure adequate support of life and safety protocols.

The standard recommends considering the use of colored cables, colored jacks or keyed connectivity to maintain segregation. Environmental Considerations TIA recognizes that some locations in healthcare facilities may be sensitive to atmospheric contamination, high levels of EMI, radiation, high temperature, chemicals, etc. To minimize these effects, the standard recommends that solutions, design and installation should be compatible with the surrounding environment.

What s the Same? Topology and Length TIA specifies the same hierarchal star topology requirements and backbone and horizontal cable lengths for healthcare facilities as specified in commercial building standards. Transmission Performance and Test Requirements TIA refers back to commercial cabling standards for all performance and testing specifications for copper and optical fiber cable and connectivity.

What s Not Covered? Harsh Environment Protection TIA does not specify what components to use for harsh environments subject to impact, humidity, strong disinfectants, harsh cleaners or wash downs.

It does specify that cabling solutions, design and installation methods compatible with the environment should be selected in order to support adequate performance in these areas during operation. Aesthetics TIA does not specifically address aesthetics when designing cabling aansi for healthcare facilities. Environmental Design TIA does not specifically address green building design considerations such as the use of reduced packaging, recycled materials or environmentally-friendly components.

To support healthcare technology needs and IP convergence, the new TIA standard addresses the need for cabling infrastructures to provide performance and reliability, increased cabling density and room for growth. It also makes key recommendations regarding design and installation practices based on specific healthcare environments and applications.

Accordingly, some infrastructure design and installation considerations remain the same between the two standards, while some are new and others are simply not covered. Responding to Healthcare Challenges While the new TIA standard is changing how healthcare network infrastructures are designed and deployed, holistically addressing information technology needs for evolving healthcare tai-1179 involves much more it requires identifying and understanding all the challenges healthcare facilities face in deploying cabling infrastructures to support the latest clinical and non-clinical applications.

Following are the key cabling infrastructure design and installation considerations for today s healthcare facilities.

In addition, one patient case can contain 30 or more images, for a total of MB worth of information per patient.

In an emergency healthcare situation, that amount of time can mean the difference between life and death. Maximum Reliability Healthcare facilities are different from commercial buildings because they provide essential services necessary to ensure life and safety.


Many areas, particularly critical care areas, can be severely impacted by network downtime. As a result, the TIA standard makes provisions for route diversity and redundancy by requiring a minimum of two diverse cabling pathways between the main service entrance facility, data center, telecommunications rooms and any space considered a critical care area. Healthcare facilities are increasingly deploying Power over Ethernet PoE technology that supplies power to a variety of devices over the same cabling that connects the device to the network, eliminating the need for costly power outlets and enabling scalability.

In the standard, the term work area takes on a broader scope depending on the healthcare environment and functions. With higher densities, more cabling resides in the pathway between telecommunications rooms and healthcare spaces. Cabling for the various systems must be able to share the pathway without experiencing performance degradation.

How much separation is required between communications cables and power cords?

ta-1179 In TRs and data centers, where cabling terminates to patch panels tia-179 connecting to switches and routers, higher-density solutions are needed to manage the higher number of terminations in less space. Maximum Safety, Security and Administration Because healthcare networks directly tiq-1179 life systems, safety, ttia-1179 and administration are of particular importance. In some areas of a healthcare facility, such as pediatrics and psychiatric wards, it may be appropriate to deploy tamper-proof work area outlets to avoid damage to network connections and the associated downtime and maintenance costs required to replace them.

The TIA standard recommends the use of colored cables, colored jacks or keyed 5. Within the various environments, the TIA recommended outlet density varies depending on the function performed at that location, as shown in the table below.

Since adding outlets after initial construction can be complex and disruptive to a healthcare facility, the standard recommends that designers select a number between the midpoint and upper end of the range if no other guidance or direction is provided. The outlet density ranges are as follows: TIA also recommends considering the use of automated infrastructure management systems to further enhance administration. Sustainability and Growth Sustainable facilities are designed and deployed in such a way that they meet both present and future needs, reducing future costs ansk with frequent upgrades.

This recommendation supports a migration to IP convergence and future clinical applications without having to disrupt rooms, hallways and other areas within a healthcare facility. Cabling pathways, spaces and components also should accommodate growth and not compromise a facility s current and future operation.

Infection Control There are many sources of infection in hospital environments, and not all are related to clinical services. For example, the dust and contaminants in the plenum space can be a source of infectious diseases. All work with a hospital anis is therefore subject to Infection Control Ansl ICR procedures, including tia-11779 infrastructure moves, adds and changes. For example, ICR procedures for opening the plenum space can include restricting the number of ceiling tiles that can be removed, how long they are removed, and procedures for cleaning the air and personnel in the work area.

Reusing cabling products e. Compatibility with these environments can be achieved with enhanced cabling components, or through protection, separation or isolation.

Accordingly, the standard recommends testing the cabling performance during operation of certain equipment, especially in the case of MRI and related machinery. Harsh Environment Protection From food service and utility rooms, to sterile zones like emergency and operating rooms, many areas of a healthcare facility are considered a harsh environment due to exposure to high temperatures, impact, humidity, strong disinfectants, harsh cleaners or wash downs.

Chemicals used in disinfectants and harsh cleaners can degrade plastics and corrode network connections and faceplates, requiring durable infrastructure components specifically designed to resist abuse and corrosion and maintain reliability in these spaces. In addition, some healthcare areas may undergo wash downs, requiring IPrated waterproof industrial network components.

Wireless Mobility Healthcare facilities increasingly need to support a variety of wireless and mobile applications. Doctors and nurses are using wireless devices for voice communication, paging and access to clinical information systems, while patients and visitors are demanding wireless access to the Internet for all the comforts of home. Moreover, the networks themselves must accommodate needs for portable medical equipment like portable X-ray, ultrasound or C-arm systems.

Aesthetics Evidence suggests that design elements can improve patients health and morale. Surveys actually demonstrate that patients in welldecorated facilities rate their care more highly than patients in unappealing settings. To remain competitive, healthcare facilities are choosing aestheticallypleasing infrastructure connectivity tia-11779 that can help maintain a uniform look throughout administration areas, auditoriums, conference rooms, lobbies, patient rooms and common areas.

Environmental Considerations As seen in commercial construction, healthcare facilities are also receiving incentives to ensure environmentally-friendly construction i.
